The World Anti-Doping Agency (WADA) has published the List of Prohibited Substances and Methods for 2020, which comes into effect on 1 January 2020. The key updates to the 2020 Prohibited List are listed below:

Substances And Methods Prohibited At All Times (In- and Out-of-Competition)

M2: Chemical and Physical Manipulation
Protease prohibition refers only to the tampering of samples. The wording for “proteases” was changed to “Addition of proteases to Sample”. Topical and systemic therapeutic use of proteases are not prohibited.

M3: Gene and Cell Doping

“Gene silencing” and “gene transfer” were added as further examples of gene doping methods.

Reiterating the statement in the Prohibited List Q & A, non-transformed stem cells, used alone (with no growth factors or other hormones added) for healing injuries are not prohibited, as long as they return the function of the affected area to normal and do not enhance it.

Substances And Methods Prohibited In-Competition

PROHIBITED SUBSTANCES

S6: Stimulants

Octodrine [1,5-dimethylhexylamine] was added as an example of Specified Stimulants, since this substance was recently found in some dietary supplements.

Administration of imidazole derivatives is not prohibited when used by dermatological, nasal and ophthalmological routes.

S7: Narcotics
All optical isomers are prohibited.

S8: Cannabinoids
Cannabidiol [CBD] is not prohibited. However, athletes should be aware that some CBD products extracted from cannabis plants may also contain THC that could result in a positive test for a prohibited cannabinoid.
